A clock has four hands, namely the minute hand, second hand, hour hand, and timer hand.

The second hand, thin and long, moves fast, rotates for 60 seconds. The minute hand is slightly shorter and centered. The second hand rotates one circle and the minute hand moves one grid. 60 seconds equals 1 minute. The hour hand is relatively short and thick. A minute hand that moves in one circle is equivalent to 60 minutes, and 60 minutes is equivalent to one hour of clockwise movement. The timer pin, also known as the alarm pin, is used to set the alarm for a fixed time. It is used to set the ringtone at a fixed time and will ring when the timer is set. The task is relatively simple.

Precautions for wearing a watch:

1. Avoid wearing a mechanical watch to take a hot bath or sauna

Generally speaking, considering the convenience of daily life, mechanical watches are often equipped with a certain waterproof scale, which can perfectly cope with domestic water use, and even swimming or diving is not a problem. But you need to always remember that even waterproof watches are not suitable for use in hot water baths, saunas, or environments with significant temperature changes. This is because of the difference between water and steam. Waterproof watches can be waterproof but cannot release steam. When wearing a hot bath, the waterproof rubber ring of the watch will expand and shrink due to temperature, causing gaps and accelerating aging, leading to water ingress and the appearance of water condensation inside the watch, which can seriously damage the components.

2. To avoid the watch being left idle for a long time and still being wound or charged with a battery

In real life, there are often various situations where your watch needs to be idle for a while. Whether it is a watch movement that relies on quartz oscillation or mechanical winding, long-term storage can affect or even damage its performance.

3. Avoid the watch being exposed to strong magnetic fields

This issue is often the most easily overlooked and invisible threat for everyone. Because the mechanism is made of steel, we all know that once steel comes into contact with a magnet, it will also generate some magnetic force, which will seriously affect the operation of the mechanical mechanism. So in daily life, one thing to pay attention to is avoiding magnetic fields, such as speakers, handbag buckles, refrigerator doors, diary buckles, security scanning sticks, and so on. Once magnetized, it is necessary to immediately send it to a professional clock repair point for demagnetization maintenance.
